摘　　要：针对目前深松作业中耕作阻力过大、深松铲磨损严重等问题,课题组应用高压气流土壤劈裂理论,借鉴仿生学原理,建立耦合数学模型,揭示气压耦合深松复杂应力作用下深松铲受力特性,确定最优减阻效能目标函数,利用遗传算法进行拓扑优化,以期得到气压耦合海豚深松铲关键部件结构最优减阻参数,为耦合式仿生海豚深松铲的研制及推广提供科学依据。In view of the problems of excessive tillage resistance and serious wear of subsoiling shovel in current subsoiling operations,the research group applied the soil splitting theory of high pressure air flow and the principle of bionics to establish a coupling mathematical model,revealed the mechanical characteristics of the subsoiling shovel under the complex stress of air pressure coupling subsoiling,determined the objective function of the optimal drag reduction efficiency,and used genetic algorithm to optimize topology,in order to obtain the structure of the key components and the optimal drag reduction parameters of the pneumatic coupling dolphin subsoiling shovel,and provide a scientific basis for the development and popularization of the coupling bionic dolphin subsoiling shovel.
